Dublin was the boyhood home of legendary golfer Ben Hogan, who was born on August 13, 1912, at the hospital in nearby Stephenville. Hogan lived in Dublin until 1921, when he and his family relocated to Fort Worth.

Dublin is the birthplace of Lt. Col. George Andrew Davis, Jr., who was awarded the Medal of Honor for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty on 10 February 1952, near Sinuiju-Yalu River area in North Korea. Davis ranks sixteenth on the list of most highly decorated U.S. military personnel of all time who received the Medal of Honor.

In 2005, GovernorRick Perry signed a bill that designated Dublin as the official Irish Capital of Texas. Thus Dublin is known to be home to many people of Irish American descent.
